[0066] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0067] Example 1

[0068] like Figure 1 to Figure 2 As shown, the battery box unlocking control system includes a push tray box 1 and a first controller 2. The push tray box 1 includes a push tray box body 11 and a suction cup 12. The suction cup 12 is telescopically arranged on the surface of the push tray box body 11; the first controller 2 is used to drive the push tray box 1 forward so that the suction cup 12 of the push tray box 1 fits with the battery box 4.

[0069] When the battery box 4 needs to be taken out of the battery compartment 7, the first controller 2 drives the tray pushing box 1 forward until the suction cup 12 of the tray pushing box 1 fits with the battery box 4. The tray pushing box 1 is connected to the battery box 4 as a whole, and the first controller 2 controls the tray pushing box 1 to return, so that the battery box 4 can be pulled out of the battery compartment 7.

[0070] like Figure 3 As shown, the battery box unlocking control system also includes a first detection unit 3, which is used to send a first signal to the first controller 2 after detecting that the suction cup 12 is retracted to a first predetermined position. The first controller 2 is also used to stop driving the push-disc box 1 forward after receiving the first signal.

[0071] After the first controller 2 pushes the tray pushing box 1 forward and makes the suction cup 12 of the tray pushing box 1 contact with the battery box 4, in order to determine whether the tray pushing box 1 and the battery box 4 are in place, the suction cup 12 is set to be able to further retract into the tray pushing box body 11, and a first detection unit 3 is set to detect the position of the retracted suction cup 12. The first predetermined position detected by the first detection unit 3 is the position where the suction cup 12 is retracted into place. The first detection unit 3 detects that the suction cup 12 retracts to the first predetermined position, proving that the suction cup 12 is retracted into place, and at this time the first detection unit 3 sends a first signal to the first controller 2, and the first controller 2 stops driving the tray pushing box 1 forward after receiving the first signal.

[0072] In addition, the first controller 2 is also used to control the disk pushing box 1 to return after stopping driving the disk pushing box 1 to advance. After the disk pushing box 1 stops advancing, the first controller 2 can also control the disk pushing box 1 to return.

[0073] The specific method of the first controller 2 driving the disk pusher 1 to move forward or backward is to use gears and racks to guide the moving direction of the disk pusher 1 and drive the disk pusher 1 to move by a driving motor.

[0074] By setting the suction cup 12 to retract a certain distance into the push plate box 11, and detecting the preset stop position through the first detection unit 3, the push plate box 1 can move forward a certain distance after the push plate box 1 is fitted with the battery box 4, thereby ensuring the tightness of the fit between the push plate box 1 and the battery box 4, and at the same time allowing the push plate box 1 to have a certain buffer distance before stopping, thereby ensuring that the push plate box 1 can achieve a safe stop.

[0075] Example 2

[0076] like Figure 4 and Figure 5 As shown, the battery box unlocking control system of this embodiment is a further improvement of embodiment 1.

[0077] The battery box unlocking control system also includes a third detection unit 5, which is located on the surface of the push tray box 11 facing the battery box 4. The third detection unit 5 is used to detect whether the distance between the battery box 4 and the push tray box 1 exceeds a predetermined value when the push tray box 1 returns. If so, a disengagement signal is sent to the first controller 2, and the first controller 2 is used to pause the return of the push tray box 1 after receiving the disengagement signal.

[0078] After the tray pushing box 1 is attached to the battery box 4, the tray pushing box 1 is connected to the battery box 4. When the first controller 2 drives the tray pushing box 1 to return, it drives the battery box 4 to return together. In this process, the third detection unit 5 detects the position of the battery box 4. When the distance between the battery box 4 and the tray pushing box 1 exceeds a predetermined value, it means that the battery box 4 is separated from the tray pushing box 1. The third detection unit 5 sends a separation signal to the first controller 2. After receiving the separation signal, the first controller 2 suspends the return of the tray pushing box 1. Through the third detection unit 5, during the return process of the tray pushing box 1, an alarm can be issued for the abnormal situation that the battery box 4 is separated from the tray pushing box 1.

[0079] Example 3

[0080] like Figure 6 As shown, the battery box unlocking control system of this embodiment is a further improvement of embodiment 1.

[0081] The battery box unlocking control system also includes a fifth detection unit 6, which is used to detect whether the disk push box 1 reaches the second extreme position during the return process. If so, a second pause signal is sent to the first controller 2. The first controller 2 is also used to pause the return of the disk push box 1 after receiving the second pause signal.

[0082] The second limit position is the limit position that the disk pusher 1 can reach during the return process. If the fifth detection unit 6 detects that the disk pusher 1 reaches the second limit position, a second pause signal is sent to the first controller 2, and the first controller 2 pauses the return of the disk pusher 1 after receiving the second pause signal. By providing the fifth detection unit 6, the disk pusher 1 can be prevented from exceeding the limit position during the return process, thereby ensuring the safety of the disk pusher 1 during operation.

[0083] Example 4

[0084] like Figures 7 to 10 As shown, the battery box unlocking control system of this embodiment is a further improvement of embodiment 1.

[0085] like Figures 7 and 8 , Fig.10 As shown, the push-disk box 1 also includes a magnetic controller 13, and the suction cup 12 is an electromagnetic suction cup. The magnetic controller 13 is used to control the suction cup 12 to be powered on after receiving a first signal; the battery box 4 includes a magnetic disk 41, and the magnetic disk 41 of the battery box 4 is used to fit with the suction cup 12 of the push-disk box 1.

[0086] When the first detection unit 3 sends the first signal to the first controller 2, the first signal is also sent to the magnetic controller 13. When the first detection unit 3 sends the first signal, it indicates that the suction cup 12 has retracted to the first predetermined position. At this time, the magnetic controller 13 controls the suction cup 12 to be powered on, and the suction cup 12 generates magnetic force, so that the suction cup 12 and the magnetic disk 41 are attracted.

[0087] like Figures 7 to 9 As shown, the battery box 4 also includes a lock tongue 42 and a button 43, the lock tongue 42 cooperates with the lock seat 71 of the battery compartment 7, and the button 43 is connected to the lock tongue 42; the push plate box 1 also includes a push rod 14 and a second controller 15, the second controller 15 is used to control the extension and retraction of the push rod 14, and the push rod 14 is used to drive the lock tongue 42 to disengage from the lock seat 71 after pressing the button 43. After the push rod 14 is extended, when the push plate box 1 fits with the battery box 4, the push rod 14 presses the button 43, the lock tongue 42 retracts and disengages from the lock seat 71, and the battery box 4 can be pulled out of the battery compartment 7.

[0088] The second controller 15 is connected to the first controller 2 in communication; the first controller 2 is used to send a second signal to the second controller 15 when driving the disk push box 1 to advance to the second predetermined position, and the second controller 15 is used to control the push rod 14 to extend after receiving the second signal. The second predetermined position can be set to a position where the disk push box 1 is closer to the battery box 4, for example, the push box 1 is about 200 mm away from the battery box 4. When the disk push box 1 advances to the second predetermined position, the first controller 2 sends a second signal to the second controller 15, and the second controller 15 controls the push rod 14 to extend, so that when the disk push box 1 is subsequently fitted with the battery box 4, the push rod 14 presses the button 43 to retract the lock tongue 42 and disengage from the lock seat 71.

[0089] The battery box unlocking control system also includes a second detection unit 8, which is used to send a permission signal to the first controller 2 after detecting that the lock tongue 42 and the lock seat 71 are in a disengaged state. The first controller 2 is also used to determine whether the permission signal is received after stopping the advancement of the push disk box 1. If so, it controls the push disk box 1 to return.

[0090] When the second detection unit 8 detects that the lock tongue 42 and the lock seat 71 are in the disengaged state, it sends a permission signal to the first controller 2, and the first controller 2 controls the disk ejecting box 1 to return. If the second detection unit 8 does not send a permission signal to the first controller 2, it means that the lock tongue 42 and the lock seat 71 have not yet been disengaged, and the battery box 4 and the battery compartment 7 are still in the locked state. At this time, the first controller 2 prohibits the control of the disk ejecting box 1 to return.

[0091] Example 5

[0092] like Fig.11 As shown, the battery box unlocking control system of this embodiment is a further improvement of embodiment 1.

[0093] The battery box unlocking control system also includes a fourth detection unit 9, which is used to detect whether the disk push box 1 reaches the first limit position during its advancement. If so, a first pause signal is sent to the first controller 2. The first controller 2 is also used to pause the advancement of the disk push box 1 after receiving the first pause signal.

[0094] The first limit position is the limit position that the disk pusher 1 can reach during the forward movement. If the fourth detection unit 9 detects that the disk pusher 1 reaches the first limit position, a first pause signal is sent to the first controller 2, and the first controller 2 pauses the forward movement of the disk pusher 1 after receiving the first pause signal. By providing the fourth detection unit 9, the disk pusher 1 can be prevented from exceeding the limit position during the forward movement, thereby ensuring the safety of the disk pusher 1 during operation.

[0095] Example 6

[0096] like Fig.12 As shown, this embodiment is a battery box unlocking control method, which can be applied to the above-mentioned battery box unlocking control system.

[0097] The battery box unlocking control method comprises the following steps:

[0098] Step 101, when the suction cup 12 of the tray pushing box 1 is in contact with the battery box 4, the tray pushing box 1 is controlled to continue to move forward so that the suction cup 12 is retracted into the tray pushing box body 11;

[0099] Step 102, detecting whether the suction cup 12 is retracted to the first predetermined position, if yes, executing step 103, if no, executing step 101;

[0100] Step 103, control the disk pusher box 1 to stop moving forward.

[0101] Through the above method, the push plate box 1 can move forward a certain distance after being fitted with the battery box 4, thereby ensuring the tightness of the fit between the push plate box 1 and the battery box 4. At the same time, the push plate box 1 has a certain buffer distance before stopping, thereby ensuring that the push plate box 1 can achieve a safe stop.

[0102] Among them, when the tray pushing box 1 stops moving forward in step 103, the following steps are also included: Step 1031, control the tray pushing box 1 to return. After the tray pushing box 1 stops moving forward and the tray pushing box 1 is connected to the battery box 4, it is also necessary to control the tray pushing box 1 to return and take the battery box 4 out of the battery compartment 7.

[0103] The execution process of step 1031 further includes the following steps: detecting whether the distance between the battery box 4 and the disk pushing box 1 exceeds a predetermined value, and if so, pausing the return of the disk pushing box 1. During the process of the disk pushing box 1 driving the battery box 4 to return, if it is detected that the distance between the battery box 4 and the disk pushing box 1 exceeds a predetermined value, it means that the disk pushing box 1 is separated from the battery box 4, and at this time, pausing the return of the disk pushing box 1.

[0104] The execution process of step 101 further includes the following steps: detecting whether the disk pusher 1 reaches the second limit position, and if so, pausing the return of the disk pusher 1. The second limit position is the limit position that the disk pusher 1 can reach during the return process. During the return process of the disk pusher 1, if the disk pusher 1 exceeds the second limit position, it is necessary to suspend the return of the disk pusher 1 to ensure the safety of the disk pusher 1 during operation.

[0105] In step 101, the suction cup 12 of the tray pushing box 1 is fitted with the magnetic disk 41 of the battery box 4; in step 13, after the tray pushing box 1 is controlled to stop moving forward, the suction cup 12 is also controlled to be powered on. When the tray pushing box 1 stops moving forward, the suction cup 12 of the tray pushing box 1 is fitted with the magnetic disk 41 of the battery box 4, and the suction cup 12 is powered on, so that suction is generated between the suction cup 12 and the magnetic disk 41 and they are attracted to each other.

[0106] Among them, in step 101, after the suction cup 12 of the push plate box 1 is attached to the battery box 4, the control push rod 14 presses the button 43, so that the button 43 drives the lock tongue 42 to disengage from the lock seat 71. Before the suction cup 12 of the push plate box 1 is attached to the battery box 4, the lock tongue 42 is locked in the lock seat 71, so that the battery box 4 is fixed in the battery compartment 7. After the suction cup 12 of the push plate box 1 is attached to the battery box 4, the control push rod 14 presses the button 43, drives the lock tongue 42 to disengage from the lock seat 71, and the push plate box 1 can pull the battery box 4 out of the battery compartment 7.

[0107] Before step 101, the following steps are also included: before the suction cup 12 of the disk pushing box 1 fits with the battery box 4, the push rod 14 is controlled to extend. During the forward movement of the disk pushing box 1, the push rod 14 is extended in advance to prepare for the push rod 14 to press the button 43 in time.

[0108] After step 103, the following steps are further included: step 104, detecting whether the lock tongue 42 and the lock seat 71 are in a disengaged state, and if so, controlling the disk push box 1 to return. Before controlling the disk push box 1 to return, first detect whether the lock tongue 42 and the lock seat 71 are in a disengaged state, that is, detect whether the disk push box 1 and the battery box 4 are in a disengaged state. Only when the disk push box 1 and the battery box 4 are in a disengaged state, can the disk push box 1 be controlled to return.

[0109] Before step 101 , the following steps are also included: step 100 , controlling the disk pushing box 1 to move forward until the suction cup 12 of the disk pushing box 1 fits with the battery box 4 .

[0110] The execution process of step 100 further includes the following steps: detecting whether the disk pusher box 1 reaches the first limit position, and if so, pausing the advancement of the disk pusher box 1. The first limit position is the limit position that the disk pusher box 1 can reach during the advancement. If the disk pusher box 1 reaches the first limit position, pausing the advancement of the disk pusher box 1, thereby ensuring the safety of the disk pusher box 1 during operation.

[0111] Example 7

[0112] This embodiment is a battery box unlocking control method, which can be applied to the above-mentioned battery box unlocking control system.

[0113] like Fig.13 As shown, the battery box unlocking control method includes the following steps:

[0114] Step 200, control the tray pushing box 1 to move forward until the suction cup 12 of the tray pushing box 1 fits with the battery box 4;

[0115] Step 300: When the suction cup 12 of the tray pushing box 1 is in contact with the battery box 4, the first controller 2 controls the tray pushing box 1 to continue to move forward, so that the suction cup 12 is retracted into the tray pushing box body 11;

[0116] Step 400, the first detection unit 3 detects whether the suction cup 12 is retracted to the first predetermined position, if yes, execute step 500, if no, execute step 300;

[0117] Step 500, control the disk pusher box 1 to stop moving forward and return.

[0118] Among them, Fig.14 As shown, step 200 includes the following steps:

[0119] Step 201, controlling the disk pusher 1 to move forward through the first controller 2;

[0120] Step 202, when the disk pusher 1 moves forward to the second predetermined position, the first controller 2 sends a second signal to the second controller 15, and the second controller 15 controls the push rod 14 to extend;

[0121] Step 203, the fourth detection unit 9 detects whether the disk pusher 1 reaches the first limit position during the forward movement, if yes, execute step 204, if no, execute step 205;

[0122] Step 204: the fourth detection unit 9 sends a first pause signal to the first controller 2. The first controller 2 pauses the advancement of the disk pusher 1 after receiving the first pause signal. This indicates that the advancement of the disk pusher 1 is abnormal and needs to enter the abnormality handling process.

[0123] Step 205 , the disk pushing box 1 continues to move forward until the suction cup 12 of the disk pushing box 1 fits with the battery box 4 , the push rod 14 presses the button 43 , and the lock tongue 42 retracts and disengages from the lock seat 71 .

[0124] Among them, Fig.15 As shown, step 500 includes the following steps:

[0125] Step 501, the first detection unit 3 sends a first signal to the first controller 2 and the magnetic controller 13.
